We divide 20893593 by 657
The aim is to understand the frequency of 657 in 20893593.

On to step 1:
When dividing 2 by 657, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 657

Step 2:
The number 657 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 657

Advancing to step 3:
657 can be fit into 208 0 times, resulting in a remainder of 208.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 208 and we're left with 208.
Bring next digit (9) of the dividend behind the 208 and repeat the process: 2089 / 657

Step 4:
2089 divided by 657 is 3 with a remainder of 118.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 1971 from 2089 and we're left with 118.
Include the next digit (3) from the dividend after 118, then repeat: 1183 / 657

Moving on to step 5:
The number 657 fits into 1183 1 times, leaving a remainder of 526.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 657 from 1183 and we're left with 526.
Append the next digit (5) from the dividend to 526 and continue with: 5265 / 657

Moving on to step 6:
If we divide 5265 by 657, we get 8 and a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 318.0
If we subtract 5256 from 5265, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 657

Going ahead to step 7:
99 divided by 657 is 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 3180.0
The remainder is 99 after subtracting 0 from 99.
Grab the next digit (3) from the dividend, add it to 99, then carry on: 993 / 657

On to step 8:
657 can be fit into 993 1 times, resulting in a remainder of 336.
Use 1 as the next digit of our solution. 
Result so far: 31801.0
Subtracting 657 from 993 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 9:
If we divide 3360 by 657, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 31801.5
Subtracting 3285 from 3360 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 10:
657 can be fit into 750 1 times, resulting in a remainder of 93.
Use 1 as the next digit of our solution. 
Result so far: 31801.51
Subtract 657 from 750 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 11:
The number 657 fits into 930 1 times, leaving a remainder of 273.
Write down 1 as next digit of the result. 
Result so far: 31801.511
Subtract 657 from 930 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

In conclusion, the division gives 31801.511 with a balance of 0.0273.
